401k After-Tax Contribution to Roth IRA

Client had a 401k with pre and after-tax contributions. The company sent the pre-tax money directly to the client’s account with custodian. However, the client received a check for the after-tax money and deposited it into his bank account. The client is thinking about keeping a small portion of this cash and sending the remainder to his Roth IRA. Is this OK to do or does this mess up the ability to rollover to his Roth?



It is OK to keep some cash and rollover the rest to the Roth IRA within 60 days from receipt of the after tax distribution. The portion kept will not be subject to tax or penalty, but the amount rolled over must be reported on line 4c of Form 1040 with “rollover” entered next to 4d. This will be a non taxable rollover to the Roth IRA, so there will not be a 5 year holding period to withdraw the Roth rollover money. Client needs to update the basis tracking for his Roth IRA unless his Roth is already qualified.

  • The entire amount distributed from the traditional 401(k) (the sum of the box 1 amounts from both of the Forms 1099-R, one with code G for the portion directly rolled over and the other with code 1, 2 or 7 for the after-tax portion) must appear on 2019 Form 1040 line 4c.
  • If the check for the after tax money was instead supposed to be part of the direct rollover, included on the code G Form 1099-R instead of on a separate code 1,2 or 7 Form 1099-R, the check should have been deposited directly into the Roth IRA.

Hi DMx,I’m confused about the second bullet point. The client rolled everything out – pre and post tax. The company did a direct rollover to his IRA for the pre-tax and earnings on after-tax. But, for some reason, sent him a check for after-tax contributions.

I’m dealing with this same issue, helping a client roll out of a plan in which she has a good chunk in after-tax, some even pre 87 aftertax.  So a check that consists of after-tax contrbutions that is distributed/payable to a client can then be rolled over into a ROTH if it’s within the 60 day rollover window?  I assume you would agree that it’s probably best practice to ask the plan admin to make the check payable to the clients ROTH IRA so there’s no question it’s being directly transferred to a ROTH IRA.  As an aside, I haven’t had to deal with “after-tax” money for clients, as its fairly rare, the ability to transfer those after-tax contributions into a ROTH with no tax consquences is huge, is it not? 

Thanks so much for all of the responses! Always helpful.
